For the purpose of these qualifications all plants have been grouped under headings which correspond to the assessment criteria within these qualifications. Although plants here have been listed under particular headings for convenience, they may more appropriately be listed under different headings in certain localities or climatic zones. Where common names have been listed these are the preferred common names as found in the RHS Plant Finder online. Centres will be formally notified if any significant changes are made to plant, seed, diseases, disorders or beneficial animals on this list. * donotes a new addition to the plant list for this verification year Where specific cultivars are listed these are of particular merit and widely available, but for many ornamental plants ‘cv.’ is listed; this indicates that candidates should have an awareness that there is more than one widely grown cultivar but that only one cultivar chosen by the centre needs to be assessed. Where the ‘Cultivar’ (cv.) is not specified the candidate MUST record the name of the recognised cultivar chosen by their centre. Where candidates are required to identify a range of seeds by generic name (level 2) or botanical name (level 3) these specimens can be chosen from any of the plants listed within this document. It is advised that the range of seeds chosen by the centre should not include seeds that they consider could pose a significant health risk to any candidate. Centres also have some leeway in making teaching relevant to their geographical area, as the full identification list contains many more specimens than the stated number of specimens to be assessed within particular units. You can search the RHS Plant Finder online at http://apps.rhs.org.uk/rhsplantfinder Please also refer to the document ‘Assessment Information and Candidate Assessment Pro-formas’ for further details about the assessment of all units for these qualifications. © – The Royal Horticultural Society Q QCF Plants, Seeds, Pests & Diseases 2013-2014 v8 07.08.14 3 RHS Registered Charity No: 222879/SC038262 Level 1 Award in Practical Horticulture Unit: Identification of a range of common garden plants, weeds, pests and diseases. At level 1 learners are expected to be able to outline how the terms genus, species and cultivar are used in naming plants. 40 live plant specimens to be assessed in the ‘Identification of a range of common garden plants, weeds, pests and diseases’ unit. Learners will be expected to use botanical names (genus, species, cultivar/variety or commercial designates (hybrids) where appropriate). Throughout the course it is anticipated that learners will study a wider range of specimens than those assessed within this particular unit. Please refer to the RHS assessment guidance for details of specimen groupings. Learners will also be able to identify a range of pests and diseases. Level 2 Certificate in Practical Horticulture Unit: Identification of a range of common garden plants, weeds, pests and diseases. At level 2 learners are expected to understand how plants are botanically named and be able to identify a range of seeds. 110 live plant specimens to be assessed in the ‘Identification of a range of common garden plants, weeds, pests and diseases’ unit. Learners will be expected to use botanical names (genus, species, cultivar/variety or commercial designates (hybrids) where appropriate. Seeds by generic name). Throughout the course it is anticipated that learners will study a wider range of specimens than those assessed within this particular unit. Please refer to the RHS assessment guidance for details of specimen groupings. Learners will also be able to identify a range of pests, diseases and disorders and know a range of beneficial animals, birds and insects. Level 3 Certificate in Practical Horticulture Unit: Identification of a range of common garden plants, weeds, pests, diseases and disorders. At level 3 learners are expected to identify a range of plants and know their decorative merits. 115 live plant specimens to be assessed in the ‘Identification of a range of common garden plants, weeds, pests, diseases and disorders’ unit. Learners will be expected to use botanical names (genus, species, cultivar/variety or commercial designates (hybrids) where appropriate. Seeds by genus only). Learners will also be able to identify certain characteristics of those specimens. Throughout the course it is anticipated that learners will study a wider range of specimens than those assessed within this particular unit. Please refer to the RHS assessment guidance for details of specimen groupings. Learners will also be able to identify a range of pest and diseases and know their characteristics and methods of control. Learners will also be able to identify disorders and describe the appropriate treatment. © – The Royal Horticultural Society Q QCF Plants, Seeds, Pests & Diseases 2013-2014 v8 07.08.14 4 RHS Registered Charity No: 222879/SC038262 2.0: DECIDUOUS AND EVERGREEN TREES Genus Species Family Preferred Common name Acacia baileyana Mimosaceae Mimosa, silver wattle Acacia dealbata Mimosaceae Mimosa, silver wattle Acer davidii Sapindaceae Snake bark maple Acer griseum Sapindaceae Paper bark maple Acer platanoides Sapindaceae Norway maple Acer pseudoplatanus Sapindaceae Sycamore *Acer rubrum Sapindaceae Red maple Aesculus x carnea Sapindaceae Red horse chestnut Aesculus hippocastanum Sapindaceae Horse chestnut Alnus cordata Betulaceae Italian alder Alnus glutinosa Betulaceae Common alder Amelanchier canadensis Rosaceae Snowy mespilus Amelanchier lamarckii Rosaceae Snowy mespilus Betula pendula Betulaceae Silver birch Betula utilis var. jacquemontii Betulaceae Himalayan birch Carpinus betulus Betulaceae Common hornbeam Castanea sativa Fagaceae Sweet chestnut Catalpa bignonioides Bignoniaceae Indian bean tree Cercidiphyllum japonicum Cercidiphyllaceae Katsura tree Cercis siliquastrum Caesalpiniaceae Judas tree Cordyline australis 'Sundance' Asparagaceae Cabbage tree 'Sundance' Cordyline australis 'Torbay Red' Asparagaceae Cabbage tree 'Torbay Red' Crataegus laevigata cv.
